This application is a continuation of U.S. patent application Ser. No. 12/624,621, filed Nov. 24, 2009, incorporated herein by reference.

BACKGROUND OF THE INVENTION

This application has subject matter in common with U.S. patent application Ser. Nos. 12/318,471, 12/318,470, 12/318,473, 12/292,153, 12/232,505, 12/232,035, 12/149,963, 12/149,964, 12/073,095, 12/073,889, 12/007,076, 12/003,691, 12/003,809, 12/806,711, 12/806,285, 12/806,284, 12/566,322, 12/527,628, 12/527,629, 12/498,874, 12/545,992, 12/527,631, 12/502,661, 11/498,881, 11/255,981, 11/184,771, 11/152,063, 11/094,215, 11/092,742, 11/092,741, and 11/094,155.

The current invention provides a projection assembly for a variety of LED (light emitting diode) lighting devices, including seasonal light string, seasonal desk-top light, seasonal ornament, seasonal door decorative item, seasonal garden light, seasonal outdoor lighting, LED lighting fixture, LED track light, LED USB light, LED battery-operated light, seasonal tree-top light, seasonal wall light device, and seasonal outdoor device. None of these light devices have a projection function. Instead, they just offer illumination. They are too limited for application and do not meet green concept. This invention enables a projection assembly to be added-on or built-into the existing variety of LED lights to not only can offer the original light function for illumination but also to add the ability to project an advertisement, seasonal image, promotion, message, electronic photo album, or other desired image to a preferred location.

The market place already includes a lot of projection clocks, projection pens, an slide projection machines, but all of these known devices use very complicated optics lenses.

The current invention applies an LED that has a diameter of 5 mm with super high brightness and low cost. This is not the same as other conventional market items using 1 Watt LEDs that have a high cost and power consumption. The updated LED used by the invention is from Japan Nichia Co., which offers low power consumptions ¼ W and ½ W LEDs having top quality with a high brightness for a long period of time. This save a significant amount of expense and power compared with prior projection toys or, business projection machines using greater than 1 Watt LED.

The current invention also applies a most economical projection assembly with as few as a single optics lens inside a tubular-housing to create a long distance image on a desired surface such as a ceiling, walls, ground, garage door, front door, outdoor walls, or patio.

The current invention also provides an add-on or built-in projection assembly for an existing LED light that can enhance the existing LED light to include additional functions without having a lot of tooling charges. For example, the invention can be used to add functions to products such as an LED track light, LED seasonal light string, LED lighting fixture, a plurality of LED light devices, and LED lights having more than one LED.

The current invention also provides a universal projection assembly that can be applied to a variety of LED lights. For example one standard projection assembly according to the invention can be put into different seasonal LED light devices including an LED light set, LED light string, tree top LED light, ornaments, Christmas tree ball LED light, front door LED light, garden LED light, garage LED light, patio LED light, outdoor LED light, and LED track light. This will save a lot of R&D and tooling charges because of the uniformity of the projection assembly.

The current invention also provides a special attachment means to allow people to add a projection assembly to one of the LEDs of an LED light string and that enables the projection assembly to be fixed at a certain angle, or adjusted to another angle at any time by adjustable attachment means. This will allow the traditional seasonal LED light string to no longer just save power consumption but also to deliver a seasonal message. A certain number of projection assemblies may be added-on or built-into the normal seasonal light string, which can include (1) a 10 piece LED light string or a 20, 30, 40 piece LED light string which may use battery power pack; (2) a 50 piece LED light string or 100 piece LED light string which may use 2.5 Volt input current, (3) a 35 piece LED light string or 70 piece, 105 piece, or 140 piece LED light string which uses the 3.0 Volt current.

Furthermore, the current invention also can use the same concept to add-on or build-in a proper projection assembly for an LED track light or any LED light having more than one LED. The projection assembly can be applied to any number from one to all of the lights in the track light, any number of which may be LED lights. This will very good for any existing track light because each light-unit can be added or removed from the track at any time. It will be appreciated that replacing any of the light sources to add a with a projection assembly will still fall within the current invention scope.

The projection assembly of the current invention may have a variety of different constructions, including (A) a fixed angle construction (B) a 180 adjustable angle construction (C) a construction that provides 360 degree rotation in an x-y plane with a predetermined degree of tilting with respect to the z-axis. The latter construction may be similar to that described in the inventor's U.S. Pat. No. 7,618,150 and other patent applications of the inventor. In addition, it is noted that light devices with more than one light source are described in the inventors' U.S. Pat. No. 7,455,444, and that the current invention may also use more than one LED or light source for the projection light device, with one or more LEDs having super strong brightness serving as a projection light source and other LED(s) or light sources providing at least the original light device's existing light performance and function. Still further, the current invention may also use the principles described in copending U.S. patent application Ser. No. 11/806,284, now allowed, which discloses the placement of more than one optics means in front of the LED(s) of a projection assembly for a related night light application.

The current invention may use the principle, disclosed in a number of copending applications and patents of the inventor, of a “sealed-unit” which includes all electrical components and has its own safety certification so as to eliminate the need for separate certification when non-electrical elements are added to make a final light device. The sealed unit may have any desired combination of LEDs, circuit means, sensor means, switch means, conductive means, and prong means, wires or pig-tail sets or conductive arrangements for connection to a power supply.

Details of the various embodiments that provide the above-listed improvements are discussed below in connection with the accompanying drawings:

FIG. 1 shows a seasonal tree top ornament with three projection assembly (12) (13) (14) arranged on top and at two side locations of a star (10) with a tree-top base (11) that enables installation on a tree or other surface. The three projection assemblies (12) (13) (14) and other light sources for star illumination are powered by a power source which may include a wall outlet, outlet device, computer, battery, solar power source, wind power source, or other kind of power source through a plug and wire (15), pig-tail set (16), USB connector (17), or any other equivalent electrical connection means.

As shown in FIG. 3, a Santa (30) has five projection assemblies (32) (33) (34) (35) (36) arranged on the head, hat, right hand, left hand, and clothes for top, sides, and ground image projection to provide five original displays. The Santa (30) has a base (31) which can fit on a desk top, dining table, closet surface, furniture, and all other desired surface and is powered by batteries, both for the projection light source for the light sources that illuminate Santa's body. The light source for the projection assembly and Santa can be LEDs or any other light source. It is to be appreciated that the lighted Santa is one preferred embodiment, which can be replaced by any kind of lighted object having an original function other than an image projection function. The current invention provides at least one projection assembly to add onto the original function of the existing lighted object and thereby increase the object's value.

FIGS. 10, 11, 12, 13, 14, and 15 all show various kinds of conventional power box and connection method to provide power for the lighted object and projection assembly of the current invention. FIG. 10 shows a battery box with a quick connector. FIG. 11 shows a compact size battery power pack having round LR 44 batteries inside and a quick connector for use with current invention. FIG. 12 shows a bigger battery box with lithium, carbonate, or alkaline batteries inside and a quick connector for connection of the power box to lighted objects and projection assemblies of the said current invention. FIG. 13 is a conventional power strip which has a plurality of outlets that can offer power to the light device of the current invention. FIG. 14 is a seasonal light strip plug with an adaptor device which also can offer power to the light device of the current invention when inserting a proper conductive connector into the adaptor (14-1) (14-4′). FIG. 15 shows a conventional pig-tail set of seasonal light strings, and one base (15-1) to receive the pig-tail end (15-4) which has an LED or light source socket (15-7) to receive an LED, bulb, or other light source. Electricity is delivered from the power wire (15-2) (15-3) to the LED, bulb, or other light source or bulb through a contactor inside the base (15-1) with electric-terminals (15-6) passing though the pig-tail end (15-4). Each pig tail has a certain electric voltage as discussed as below in connection with a special attachment means to allow people to add the projection assembly to one of the LEDs of an LED light string and fix the projection assembly at a desired angle, or enable adjustment to another angle at any time by an adjustable attachment means. This allows the traditional seasonal LED light string to not just save power but also to have the seasonal message delivered to more people. This means that it is possible to add-on or build-in any desired number of projection assemblies on the normal seasonal light string, such as (1) a 10 piece LED light string or a 20, 30, 40 piece LED light string which may use a battery power pack, (2) a 50 piece LED light string or 100 piece LED light string which may use a 2.5 Volt input current, or (3) a 35 piece, 70 piece, 105 piece, or 140 piece LED light string which uses 3.0 Volt current.” Hence, the pig-tail is a good power source for low power consumption LED lights.

FIGS. 8, 9, 16, 16-1, 17-20, 20A, 20B, and 32-34 show different projection assemblies with, respectively:

-   -   (1) a fixed projection angle (FIGS. 16, 19, 20, 20A, 20B, and         32-34),     -   (2) a more than 180 adjustable projection assembly (FIGS. 17 and         18), and     -   (3) a more than 360 degree rotation about an axis and some         degree of tilting with respect to a perpendicular axis (FIGS. 8,         9, and 16-1).

As shown in FIG. 8, the projection assembly may includes a light source (85 a), optics lens (85 b), optics lens assembly, original display (85 c), tubular-housing (85), and mechanical construction (not shown) for changing the magnification of the original display, which may be selected from a slide, film, digital data, LCD screen, stencil, miniature piece, indicia, art work, design, message, words, slogan, advertisement, and/or cartoon characters for appropriate enlargement and projection to a desired location.

At least one project assembly 85 is arranged to be attached to the main-object (80) and may incorporates a corresponding mechanical construction (84 a) (84 b), electric circuit means (not shown), a digital data processor and accessories (not shown), and/or an electric device to provide a valuable appearance and function, such as fixed angle projection, (FIG. 16) (FIG. 19) (FIGS. 20,20A, and 20B) (Figs. page 32-34), adjustable angle projection (FIG. 17) (FIG. 18), a plurality of projections (FIG. 1) (FIG. 2) (FIG. 3) (FIG. 4), moving projection (FIG. 19), motion projection (FIG. 19), automatically changing projection (not shown), single image projection (FIG. 8), projection of changeable images (FIGS. 20-20B) (FIGS. 21-24) (FIGS. 25-27) (FIGS. 28-31), automatically changeable images (FIG. 19) and other desired functions. The optics lens assembly may be any combination of optics means, including those disclosed in the inventor's U.S. patent application Ser. No. 12/318,470 and U.S. patent publication No. 2009/0284960. The discussion of feature (9) at the beginning of the detailed description also refers to a very good optics-lens assembly for long distance projection of up to 10 feet, while short distance projection of less than 6 feet can use fewer lenses to save cost.

The main-object (80) of FIG. 8 and main object (80′) of FIG. 9 may be identical. As shown in FIG. 9, The main-object (80′) incorporates final-parts (90′) to make a finished product (90″) in the form of an LED light having a projection device. The LED light may be a seasonal light string (FIG. 7), seasonal desk-top light (FIG. 16), seasonal ornament (FIG. 40), seasonal door decorative items (FIG. 40), seasonal garden light (FIG. 16-1), seasonal outdoor lighting (FIG. 18), LED lighting fixture (FIG. 9), LED track light (FIG. 9), LED USB light (FIG. 5), LED battery operated light (FIGS. 3 and 6), seasonal tree-top ornament (FIGS. 2 and 4), seasonal wall light device (FIGS. 20, 20A, and 20B, 21-24, and 35-38), or seasonal outdoor device (FIG. 20-20B, 21-24, and 35-38).

As shown in FIG. 7, the projection assembly (76) (76′) (76″) can be added onto any of LED light (71), light device (71′), or bulb (71″) by quick install-means (not shown) to enable a respective at least one LED (73″), light source (73′), or bulb (73) to be incorporated into the corresponding at least one projection assembly (76) (76″) (76′). The projection assembly (76) (76′) (76″) does not need to have any light source of its own since the displays (79) are illuminated by the at least one of LED (73′), light source (77″) or bulb (73) from the LED light onto which it is retrofitted. Thus, as shown in FIG. 7, at least one of the main-objects (71) (71′) (71″) may have a projection assembly (76′) (76) (76″) with projection function incorporated into the same light string, whether the string is a 50 piece, 100 piece, or 35/70/105/140 piece string as described above.

The LED light (70) may be selected from a seasonal light string (FIG. 7), LED track light device (FIG. 9), LED light fixture (FIG. 5), LED light device or LED light having more than one LED (FIGS. 17 and 39).

FIG. 17-1 also shows at least one projection assembly (17-1 a) that is added onto or built into, and that incorporates an LED light's LED or other light source (17-1 b). An attachment means (17-1 c), (17-1 d), (17-1 e), or (17-1 f) enables the projection means (17-1 a) and the LED or other light source (17-1 b) to have a desired orientation because the swivel base (17-1 c) is connected with two end swivel rods (17-1 d) and a swivel base (17-1 e) to permit 360 degree rotation about an axis and tilting of the front projection assembly (17-1 a) to project a desired image to a preferred location with correct size and sharpness.

As shown in FIGS. 21-23, and also FIG. 39, a projection device for a variety of light devices, includes at least one sealed-unit having built-in parts and accessories selected from LEDs or other light sources, circuit means, power input-means, conductive means, a plug and wire, pig-tail socket and plug, quick electric connector, socket and plug, electric components, a mechanical projection angle adjustment assembly, and/or means to change the original display. The sealed-unit has a geometric shape design and is powered by direct or alternating current through conductive means and circuit means to obtain a trigger voltage and current for the LED or other light source. The sealed-unit with all the parts and accessories will turn on the at least one LED or other light source to project an image to a preferred location or surface according to predetermined features, function, and performance. The sealed-unit must meet all safety standards and be safety test certified so that it can be incorporated with other final parts such as the projection assembly to make finished products without the need for additional safety certification.

As shown in FIG. 16, the projection assembly may be a fixed angle type which has a left tubular housing member (16-8) and a right tubular housing member (16-8′) having an original display (16-11) that includes a plurality of slides (16-12) arranged on a wheel (16-10). Wheel (16-10) is arranged to fit into a groove (16-9) (16-9′) to complete the slide-changing function. The front optics lens is precisely positioned so as to enable the original-display (16-11) to project an image having a pre-determined size to a predetermined distance. The projection assembly (as illustrated in the rectangular inset to FIG. 16) can be arranged to form a desk top candle light set. The flame portion has a projection top (16-15′) and/or the base has two projection tops (16-15″)(16-15′″) to allow people to have a novel illuminated candle light set with three additional projection functions during the holiday season.

As shown in FIGS. 17 and 18, the projection assembly (18-5) is designed for over 180 degree or continuous rotation. Two extended elastic electric-contacts (18-3) (18-3′) on each half ball enable the ball to continuously rotate without any damage to the electric connection because the contacts are resilient. The projection assembly (18-5) of FIG. 18 is similar to projection assembly (17-7) of FIG. 17 and has a tubular housing that allows a light source (17-7 a) to emit a light beam to a first optics lens (17-1 b) and cause all light source light beams to be parallel to the original-display (17-7 c). The original-display (17-7 c) must be very precisely positioned relative to a second optics lens (17-7 d) so that the projected image from the original display will be correctly displayed. If the distance is just slightly off, the image will look very bad and be out of focus.

FIG. 19 shows an arrangement of an original-display (19 a) in the form of a screen which has changeable original display data that is continuously or periodically updated. The screen (19 a) is connected with a plurality of data delivering wires (19-13) in such a way as to leave enough space to allow the data wires to be correctly installed and make very good electric connections. In case of complicated and high volume data delivery, the projection assembly requires a special arrangement including a top tube (19-A) and lower tube (19-C). The lower tube (19-C) has a flat surface (19-3) with walls (19-4) that include terminals or poles to tightly connect with the top tube portion. The flat surface (19-3) and walls (19-4) form a recess to allow the original-display (19 a) to fit with the space and offer sufficient space to arrange a lot of data wires (19-13). The original-display of this embodiment is a screen (19-a) installed within a lower screen-holder (19-7) and top cover (19-8). The top cover (19-8) has one area (19-10) for a plurality of the screen's terminals (not shown) to connect with the data wires (19-13) using pressure-means (19-12) to press and fasten the wires (19-30 by fastening-means (19-11) (10-11′). This enables a large amount of data wires (19-13) to be provided so as to correctly deliver electric digital data to the screen and provide a changeable or movable image with sufficient resolution that it can be projected by the projection assembly to a desired location with a correct focus. The changeable digital data may be LCD display data, map data, TV image forming data, or any digital data that people might want to enlarge by projecting it to a desired location so that it can be viewed by more people.

FIG. 40 shows the illuminated ornament balls each of which has at least one projection assembly inside the ball and a hanger to allow people to hang the illuminated ornament balls on a tree, door, handle bar, nail or anywhere people like. This is the best application to add a projection assembly to an illuminated object because the object can be hung on or placed on a desk top, allowing people to find the best position to get a clear image using a pre-set focus of the project assembly, so the cost will be very low. However, other applications or embodiments may incorporate focus-adjustment of the top lens, for example by including a mechanism that can change the focus by twisting the mechanism to change the distance from the top lens distance to the display as necessary to form the clearest and sharpest image. Thus, an adjustable focus lens assembly will still fall within the scope of the current invention scope. It will also appreciated that the projection assembly may be fitted within either a base or ball of an illuminated waterball. Those skilled in the art will also appreciate that the image projected to a desired location is not limited to seasonal or holiday images but may, as shown in FIG. 41, be any kind of art, design, shape, advertisement, logo, promotion words, message, display, stencil, painting, movie, time, motion picture, digital game, or digital data display image.

As a result, the invention should not limited to the above-discussed preferred embodiments. instead, all alternative, equivalent, same function, or replaceable skills, theories, arrangements, and constructions, including any those discussed in the inventor's copending projection light applications, may still fall within the scope of the current invention.
